Weather
Light northerly winds with no transport. Warming temps, clear skies.
Snowpack
Surfaces near and above treeline are wind affected by the recent wind event. Wind slab formation is fairly easy to identify; most terrain is soft, rippled sastrugi posing no hazard, while concave terrain features and steep rollovers have stiffer, smoother pockets of drifted snow that were sensitive to ski and snowmobile cuts. Observed some rollerballs on sunny aspects, but were back at the trailhead mid-day before things warmed up too much.
Avalanche
Skier and snowmobile triggered a handful of small wind slabs on drifted features near treeline. Crowns ranged from 4? to 12? thick. They were stiff enough to break above you (generally 4F, some pockets of 1F).
